Getting through security on some Delta flights in Detroit soon may take less time.

Delta Air Lines will install facial recognition software at all 14 gates at Detroit Metropolitan Airport's McNamara Terminal. And in 2019, the software is coming to all Delta flights in Detroit.

Instead of an employee checking your face to your passport, you'll look into a screen that will produce a green check mark when you're good to go. The scanners will be rolled out throughout the entire security and boarding process, from the online check-in kiosks to the baggage counter to the TSA checkpoint.

Of course, you have to be OK with a camera capturing your face — and matching it to your passport — rather than a person. According to Delta, most people say yes: In Atlanta, where the company began rolling out the software for the first time this fall, only about 2 percent of travelers have opted not to use it.

“We’re removing the need for a customer checking a bag to present their passport up to four times per departure — which means we’re giving customers the option of moving through the airport with one less thing to worry about, while empowering our employees with more time for meaningful interactions with customers," said Gil West, Delta’s COO, in a statement.

The new software will not impact any existing jobs at the airport over the coming year, said spokesperson Kathryn Steele.

The effort comes in the midst of a larger push from U.S. Customs and Border Patrol and the TSA to use facial recognition software, and biometrics overall, in airports where the agency already takes photos of travelers entering and leaving the United States. JetBlue offers facial recognition services on some international flights, like the Fort Lauderdale, Florida, to San Jose, Costa Rica, line.

Advocates for biometrics have noted that the software has caught two people at Washington-Dulles using passports that weren't theirs.

Even if you choose to use the software, you should still get to the airport early. The new service has shaved off an average of about two seconds at boarding so far, or nine minutes when boarding a larger wide-body aircraft, Delta said.

The software comes through a partnership with the airline, CBP and the airport's manager, Wayne County Airport Authority.
